The 35kV three core intermediate joint heat shrink kit is designed specifically for the intermediate connection of 35kV power cables. It uses radiation cross-linked polyolefin heat shrink material to ensure high-strength insulation and sealing performance, and is suitable for direct burial, tunnels, and humid environments. This product has a withstand voltage level of 35kV, a temperature range of * * -40 ° C to+105 ° C * *, resistance to UV aging and chemical corrosion, and a lifespan of over 20 years. Triple protection: integrated stress control, insulation recovery, waterproof sealing layer, reducing the risk of partial discharge (<5pC). Quick installation: shrink the flame or hot air gun and complete the joint production within 30 minutes (saving 50% time compared to traditional casting). IP68 waterproof rating, suitable for coastal high salt spray and mining dust environments. Support cable cross-section of 50mm ² -400mm ².
